With American vaccine supply and access increasing by the minute, lots of people are itching to travel again -- even if not far flung. "I can't wait to travel home to see my parents for the first time in a year and a half," says Jessica D., a 31-year old nurse who was vaccinated nearly three months ago, but has been waiting for both late-60s parents to receive both doses of their own Pfizer vaccines. "I'm not looking to trek to the Himalayas, I just want to travel a few states away to see my parents because I miss them so much and have been worried about them. Hearing about a flight sale like this is really exciting. Other than seeing my parents for a week or so, I'll still be mostly home and staying responsible till the pandemic seems to be calming down."
